A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.

By differentiating equation (7), it is easy to show that the maximum turbine efficiency occurs when Ud/Uu=1/3 ( when Ad/Au=3). The efficiency is then η=16/27 ≈ 59%. This is the maximum achievable efficiency of a wind turbine and is known as the Betz limit after Albert Betz who published this result in 1920.
